AH W IF MQB W Morgan, Los'Angeles,- balif. i Application March 21, 1932; Serial No'.600, 1 4 i g"11,(claimsv,v (011145- 52) This invention relates a. an s atement at screw drivers and which is adapted to .hold a,

screw against the'blade, of a" screw ,dr'iver' "and in engagement within the kerf of'the screw'while the screw is being startedin pos'ition by'theassociated screwdriver; v i .i i Thisinvention is an improvement over my copending application Serial No, 451,324, filed May An object of this invention toprovide andv'elattachment for sorewfdriver's and which attachment may be conveniently and securely attached to and removed frornthe shank of screwdrivers I now on the market, and which be].used'-to hold the screw" while being started inhposition and Whichma'y be detached iromthefscifewcina minimum amount ofspaceg,

Another object is to provide,"anjattachment'jfor screwdrivers whereby a screw is securely held in relationfto a screw driver blade "while .the screwis being started in position, andiwhich attachment may befitted to ashankofvscrew drivers now on the market without requiring, any modification thereof, v m 7 h a ,t l i 1 A further object ,l is' to, provide" a novel, attach; ment for screwdrivers having the characteristics above set forth and *whichmay; be easily and quickly changed to adapt itself to hold screws of various diameters.

i p ha es an of bbera iori and assembly are other objectsand advantages. An advantage is that "a bifurcated foot portion is pivotally" associated with the shank or "body portion of the attachmentwherebylthe root portion is swung at right anglesto-the body por: tion so as to steady a screw when itisistarted in the'material to-which'it is; to heapplied and after the's'ame has been insertedv in the material a sufficient distance tisteady thes'crew thefoot portion may then beswung aboutitspivot so as to release the screw froin enga'gementrtherewith without requiring any'side motionor the' at'tachment, thus permitting the starting- 0f screws-with my attachment and the removal :of the-attach ment; therefrom in places -'having:v aminimum' amount of spacetherearoundm Other objects,- advantages'and features of ine n y: -.ap :f f0 thief-accompanyin .l b qieediq il des ipt on a d;.. e amiendedelaims The accompanying" drawing illustrates theinvention in some of the forms I'at present deem preferable.
